Adding Fractions

How to add fractions with unlike denominators



You multiply the denominator number by the other denominator number (like so). What you do to the bottom, you always do at the top. 

If you get the same denominator, you're doing this correctly. Now you add the two fractions together. 
Is the answer in lowest terms? If the answer is not in lowest terms, you figure out if you have to divide it by 2, 3, 5, 10 or any other numbers that works. 
You do this process until you get the answer to be in lowest terms.

 Now you're done! Here's an example below.
